Borrowing and repaying: tax classification and treatment
Drawing a loan against collateral and paying it back are classified non_taxable: loan proceeds are not income and repayment of principal is not a disposition, the same as any secured borrowing.

Tax treatment
House treatment: non_taxable for borrow, repay.
This mapping comes from the closed CryptoTaxEdge classification taxonomy: every verdict resolves to one category and one of five treatments (disposal, income, non_taxable, expense, needs_review), with a confidence score and review routing when sources disagree.
How the engine reads this shape
A borrow receives tokens plus a matching debt, so there is no accession to wealth under IRC §61. A repay extinguishes the debt with the borrowed asset. The tax-relevant edges are elsewhere: repaying with a DIFFERENT asset than was borrowed disposes of that asset, interest paid may be deductible or capitalized depending on the taxpayer’s activity, and a liquidation of the collateral is a forced disposition. The engine distinguishes these shapes by the actual token flows rather than by what the front end called the button.

Verified rules behind this category
The engine backs this category with 91 verified contract-level rules across 13 chains, each earned from repeated on-chain observation and cross-source agreement rather than a heuristic guess. A small illustrative sample:
| Protocol | Chain | Category | Confidence |
|---|---|---|---|
| multiple | ethereum | borrow | high |
| multiple | ethereum | repay | high |
| multiple | arbitrum | repay | high |
| multiple | arbitrum | borrow | high |
| multiple | polygon | borrow | high |

Limitations
What this page does not decide. Whether accrued interest is an expense, an investment cost, or nondeductible is a facts-and-circumstances call for the preparer. Liquidations and self-liquidating loan products are classified separately from the plain borrow and repay shapes shown here. Confidence is a corroboration signal, not an accuracy percentage: when independent parses of a transaction disagree, the engine returns needs_review with taxable: null rather than guessing.
Frequently asked questions
What tax treatment does this page document?
House treatment follows the CryptoTaxEdge Classification Standard. Categories with no fixed mapping (GAP-3) tell you to read the treatment field on the record rather than infer it from the category name.
Where is the closed vocabulary published?
The versioned Classification Standard at https://cryptotaxedge.com/standard/ enumerates emitted categories and the five-treatment enum. This encyclopedia page is a worked example on top of that Standard.
Are the wire examples still current?
Yes. Each example is verbatim engine output, re-verified on a daily replay against the live engine.
